In the last week or so google voice has stopped ever ending threads of conversation with each contact. It used to start a new thread daily. I'm up to 400 messages in my thread with my girl and it's starting to lag when I load voice now...anyone else experience this? Also can't seem to find a way to force the thread to end. I tried archiving it, but it comes right back when new texts come in. Searched around the google voice help forums and no answers to the issue to be found so far.
